However being new to realflow I'm slowing starting to breakdown what this scene involves.

I've got a few questions I was hoping someone could help with..

1 – How do you make the emitter emit intermittently. The demo shows bursts of bubbles rather than the default contain stream.

2 – Can you make the emitters spin without keyframing them?

3 – In the demo tutorial, the emitters seem to be below the object so by the time they turn into bubbles they are just entering the glass beaker. How do I get the particles produced by the emitter to go through the object? In my test they hit the bottom of the beaker and bounce off!

Ah, the good old pixel pro example of boiling water. The final movie is superb, but this kind-of tutorial has also sparked a lot of questions on forums since then We discussed this previously:viewtopic.php?f=31&t=7357&hilit=bubbles&start=0

Just read through this post and I think it answers some questions, but anyone help with how do you make the emitter emit intermittently. The demo shows bursts of bubbles rather than the default contain stream.

Some additional points:The bubbles from below can enter the glass beaker, because the fluid interactions of the beaker are set to "inside", therefore the beaker holds everything inside, but particles from outside can enter the vessel and become trapped inside. You can kill the bubbles at the water surface with a daemon depending on the age or if they touch a bounded k-daemon region. The mesh contains both water and bubble emitters, but with the bubbles emitter set to "subtraction". In this way the bubbles are actually never forming a mesh themselves but there are bubble-shaped cavities which travel through the water upwards.
